... efficiency of the diluent). This study provides guidelines to select one of the three following methods: diluent injection, emulsion injection or reservoir-based technology. Previous operators performed extensive reservoir characterization and simulation modeling which led to recovering over 200 million...

... The scope of this study is to investigate the emulsion formation mechanism for these three experiments. Therefore, produced oil, produced water, and the spent rock samples originated from base SAGD (E1), ES-SAGD with co-injection of n-hexane (E2), and ES-SAGD with co-injection of n-hexane and...

... creating emulsions which generate partial solubility between the oil and water phases. The second ones focus on lowering the viscosity. The objective of both systems is to increase the fluency through the oil transportation process. These types of chemical systems are usually tested on the field, measuring...
